Hi, thanks for asking in Healthcare Magic.
The eye symptoms you are mentioning is typical of Graves' disease. Bulging of eyes, redness, difficulty in seeing (
double vision or
diplopia) and swelling around eyes are present along with thyroid gland enlargement. It is an autoimmune disorder ie., stimulation of immune system that results in excessive stimulation of thyroid gland. Excess of
thyroxine (thyroid hormone) is produced by thyroid gland in Graves' disease
Anti thyroid drugs like Propyl thiouracil or
Carbimazole are used in the treatment of Graves' disease.
High iodine intake increases thyroid production. Your mother should avoid taking
iodised salt, fish and aspartame (the sweetener which triggers auto immune reaction). She should also avoid berries, tomatoes and bell peppers which will increase thyroxine level.
She can take goitrogenic food stuffs like soy products, gluten, turnip, spinach and cruciferous vegetables like cabbage, cauliflower, broccoli and brussel sprouts. These are known goitrogens and reduce thyroid hormone synthesis.
I hope this is useful to you.
